Different Types Of Water Purifiers: How Are They Different?

If you are looking for the best water filtration system for home, you may have to choose from multiple options. This is the point where most people become confused and buy a water purifier that they probably don’t need.

To make sure that you will not make the same mistake, go through the article thoroughly as we have discussed different types of water purifiers and what they do.

Reverse Osmosis (RO) Purifiers

To know the working of RO, we must first understand what Osmosis is.

Amglow Water

In the normal osmosis procedure, the water spontaneously flows from an area of low solute absorption or low TDS level, through a layer, to an area of high solute concentration or high TDS level. The pores of the layer are very tiny, mostly 0.0001 microns, through which the water molecules are permitted to advance through and the smallest dissolved contaminations and bacteria are confined.

As the name implies, Reverse Osmosis or RO does the reverse of Osmosis, which is to force the water molecules from the area of higher TDS level to the area of lower TDS level. This is accomplished by applying external compulsion with the assistance of a water pump to inverse the spontaneous flow of water. 

Water with contaminations or high TDS is regulated at high compulsion into the RO chamber, which then forces the water molecules through the semi-permeable layer to the opposite side while leaving the liquefied solids and other contaminations behind. All the liquefied solids and contaminations along with some input water, which is known as RO wastewater, are eliminated through a different outlet.

Ultrafiltration (UF)

Like RO, Ultrafiltration also applies a semi-permeable layer to cleanse water. After going through the first sentence, you must now be rationalizing if both RO and UF use the identical method to cleanse the water then what is the contradiction between RO and UF. Ultrafiltration or UF utilizes a layer with much bigger pores (approximately 0.01 microns) as in comparison to RO which utilizes a layer with very tiny pores (approximately 0.0001 microns).

The benefit of using Ultrafiltration is UF purifiers can purify water without electricity as the layer has much bigger pores and water can advance through it spontaneously utilizing the power of gravity. This denotes that no external compulsion or water pump is needed. Also, since UF purifiers do not keep any water, you will not be wasting any.

Ultraviolet (UV) Purification

 As the name signifies, Ultraviolet or UV purification utilizes ultraviolet rays for purifying the water. UV purifier channels by throwing high-intensity UV rays on the water that kills or inactivates the infectious bacteria and viruses.

However, UV purifiers cannot eliminate any liquefied or un-dissolved contaminations or chemicals from water. Due to this most of the UV purifiers that are sold in the market use some type of external dregs pre-filters to eliminate un-dissolved contaminations and activated carbon filter to eliminate Chlorine and some liquefied contaminations.

Tap/Faucet Mounted Filters or Gravity Based Water Purifiers

These types of water purifiers are easiest to use and allow the most needful water purification. 

These filters usually consist of sediment or sediment + activated carbon filters which can eliminate massive and un-dissolved contaminants like mud, sand, and even some chemicals and microorganisms. 

These filters are also called the gravity-based storage purifiers, which are the better version of tap or faucet filters. These purifiers provide a bit better purification and available with an in-built storage tank to keep impure water.
